How can I see the (program) inside of the chrome profiler?

[우지윤]

Recently I launched a game website. When I'm alone on the server, I have no problem, but if I`m in with a few users [even just five users] on the same server the performance gradually drops. [This is happening to many users who using chrome.]

 In the JavaScript profiler, there is a phenomenon that the proportion of (program) increases over time[It occupies more than 60% before clearing the some rendering function, and exceeds 90% when clearing the some rendering function. And the total cpu usage exceeds 100%.]. How can identify the inside of this (program)?

* There is no problem with other browsers (ie, firefox, opera).

* The website server uses node.js (socket.io) and the client is fully developed in JavaScript.

* Server is Ubuntu, my test environment is Windows 7, Chrome version is 64.0.3282.140.
